CHARLES P. BIGGS, OF MOUND CITY, MISSOURI, ASSIGNOR TO WILLIAM HENRY CRAWFORD, OF MOUND CITY, MISSOURI.

vELEC'JTRICAIl'iLY-I'IIEI.ATED DISPENSING PUMP.

Application led September 15 1926. Serial No. 135,624.

The object of this invention is to provide a pump especially adapted to dispense oils during cold weather,- and an apparatus in which provision is made for dispensing oil or other fluids of different grades.

A further object is to provide oil containers having transparent walls to be mounted above a housing in which a battery of pumps is installed, these pumps being of the rotary centrifugal type, if desired, and geared for operation from a single motor, any one of the pumps being placed in service at a given time, or two or morebeing operated.

A. further object is to provide thermostatically controlled electric heating apparatus, the heating units being in two groups, so that the housing for the pumps and the transparent oil containers may be heated to different temperatures, if desired.

Vlith the foregoing and other objects in view, the'invention consists in the novel construction and arrangement of ,elements described, illustrated and claimed, it being understood that modifications may be made within the scope of the claims without dcparting from the spirit of the invention.

I'n the drawings forming part of this application,

Figure 1 is a view of the apparatus in vertical section.

Figure 2 is a horizontal section on line 2-2 of kFigure 1.

Figure 3 is a horizontal section on line 3 3 of Figure 1.

Figure 4 is a diagrammatic view showing one of the thermostatically controlled heating circuits.

Figure 5 is a similar view showing another group of heating units arranged in a circuit thermostatically controlled. n

The housing-for the pumping apparatus per se is designated 1() and may include a lining 11 of insulation, this housing being adapted to support the oil containers, three of which are shown, by Way of illustration, in Figure 1,-it being understood that any suitable number may be employed. The transparent oil or fluid containers are designated respectively 13, 14 and 15, and are mounted in annular channeled elements 16 f carried by the top 17 of the lower structure,

mediate filling material 19 in which one group of heating coils is mounted.

Sections of hose 2O and 21 are connected with containers 13 and 15 andthe middle container 14 is provided with connections 22 and 23, permitting hose to be attached to either side of the apparatus or both sides.

An upper structure includes the cap 25 and the wall 26 having annular channels for the accommodation of annular insulated or packing elements 27, into which the walls of the oil containers extend. The wall 26 is provided with apertures 28, and a chamber 29 between the elementsy 25 and 26 provides space for the installation of a thermostat 30 adapted to control the heating coils for the oil containers. The thermostat 31 controls the. coils for heating the pump housing, and

further reference to these coils will be made below. Y

.The pumping apparatus includes rotary and centrifugal pumps shown conventionally at 35, 36 and 37, and these Apumps are to be driven thru suitable shafts and gearing, from motor 3S. The armature shaft 39 of motor 38 carries sprocket wheels or driving Vwheels 40 and 41 on opposite ends thereof, and chains or belts 42 and 43 are driven by the wheels just referred to, and impart rotary movement to wheels 44 and 45. lVheel 44 is on shaft 46 and -splined clutch element 47 on this shaft cooperates with clutch element 43 on shaft 49 carrying wheel 50 by means of which chain or belt 51 is driven, this element last named imparting rotary movement to wheel 52 on shaft by means of which pump 35 is operated when theclutch element 47 is thrown in by lever 54.

Also on shaft 46 is a splined clutch element 55 cooperating with clutch element 56 on shaft 57 carrying a sprocket wheel 53 for driving chain 59 and wheel 60 on shaft 61 of pump 36. The clutch element is controlled by a lever 62.

rlVheel 45 already referred to is keyed on shaft G5 and clutch element GG on this shaft is controlled by lever 67, this clutch element cooperating with clutch element 68 on shaft 69. The shaft carrying a sprocket wheel 7 O driving chain 71 for imparting movement sprocket wheel 72 on shaft 73 of pump 37.

It will be observed therefore that the pumps may be individually controlled by the levers 54;, 62 67, and. that allk of the pumps are vdriyenifrom shaft 39er" motor 5S,

The thermostat 31V in pump housing 1Q Vis illustrated inoFyigures 1 and '51 and Vcontrols the circuit"including` the resistance elements 75, suitably po-sitioned within housing 10, and itis the intent-ion thaty the circuit including` the resistance units jus'tieferredn to shallA be completed .when a predetermined loWteinperature Within the housing 10, is reached. The thermostat in the .upper portion oi' theapparatns controls the'resistancef :units '76.'forthe individual oil, containers, these resistancevunits 76 being` imbedded in the material 1 9 between Walls lor plates 17 Vand 18.

for the motor 38 is not illustrated, but Will,

ofcourserbe controlled by a suitable switch', and oil yWill be pump-,ed by the individual elements of the pumping apparatus, to the individual containers, 13,14 and 15 thru'pipes 153?, 14? Vand 15,and W ll be discharged into theupper portions of ycmitainers 15, 1eand 15, and at `points ust below the inverted fun-V nel-shaped elements 88. The pipes leading to the housings of the pumps, 36 and 37 are' designated 84, 85 and 86, these pipes leading from sourcesV of supply, suchas underground ltanks or Iother containers. O verT VtloW pipes for ,the'individualz containers 13, 141 andl, are designated 87, 88`and ,89.

The resistance units' 7 5. may be mounted inV or imbedded in an elementQD,positioned adjacent 'te the (pumps 3.5, 'and .3?, and

Yand the pipes 13', 14 andrl5rvmay'extend Haying ldescribed, the invention what claimed is 1. In an apparatus of theel-ass described,
